Did You Know That Artificial Light Can Be Just As Damaging To Polymers As The Sun?

      

UV radiation from any source breaks down chemical bonds, causing cracking, chalking, color changes, and degradation of physical properties. LOWILITE™ Hindered Amine Light Stabilizers (HALS) work by free radical scavenging to inhibit degradation of the polymer. Unlike UV absorbers, HALS are regenerated rather than consumed during the stabilization process.

Their high molecular weight means they do not migrate easily and makes them capable of providing extreme long term thermal and light stability. The HALS portfolio from SI Group™ also boasts broad food contact approvals, improved color yield in pigmented systems and resistance to acidic conditions.
